Frequency band searching and matching method of ultrasonic-wave biological treatment

Abstract

A frequency band searching and matching method of an ultrasonic-wave biological treatment is synchronized with frequency band switching of output electric energy of a driving power supply. In a pulse interval of a processing mode, a controller selects to switch a corresponding relay and a corresponding output terminal of the driving power supply is connected to a vibration plate which is connected with a corresponding tap of an inductance coil so as to realize selection switching of a corresponding inductance-vibration plate matching network. The method is characterized in that: during a stride frequency band searching and operation process of the ultrasonic-wave biological treatment, when the high-efficient processing frequency band is not detected, a concentration device switched to a frequency band switching operation working flow; an intermittent point is set in the operation process after the frequency band switching operation working flow is switched into and a step of switching to a next frequency band resonance matching network is executed; after the switching is completed, the next pulse starts and frequency band searching processing operation continues.

Description

technical field [0001] The invention relates to a frequency band search transduction matching method for ultrasonic biological treatment operation. Background technique [0002] The processing rate of ultrasonic waves on objects is highly correlated with ultrasonic frequency, and the processing efficiency varies greatly with different ultrasonic frequencies; moreover, the type of biological cells to be processed is highly correlated with ultrasonic frequency, and different biological cells are highly sensitive to ultrasonic waves of different frequencies. Not the same. This has caused the blindness of the initial ultrasonic frequency determination in the existing ultrasonic biological treatment method, and further, the additional ultrasonic frequency analysis and determination form dependence. The actual working process is: use the treatment of a certain biological cell at different frequencies, compare and analyze the sub-bands, and obtain relevant data; in the future work...

Problems solved by technology

In essence, such a method cannot guarantee that the working ultrasonic frequency is the optimal frequency for the object, nor can it perform precise and fine frequency adjustments for different objects, and the accumulated experience is not the best process; in addition, the The method not only consumes a lot of manpower, financial resources and material resources in the initial stage, but also often requires observation, adjustment and maintenance during the use period.
